Number of cuboids with dimensions

8cm x 15cm x 20cm stacked together to form a cube is

Well, stacking cuboids to form a cube is quite an interesting endeavor. It's like trying to fit a round peg in a square hole, but with mathematical dimensions. So, let's see how many of these cuboids we can squeeze into a cube!

To find out, we need to consider the common divisor of the three dimensions: 8, 15, and 20. The largest common divisor between them is 1cm. So, if we divide each dimension by 1cm, we get a new set of dimensions: 8cm/1cm, 15cm/1cm, and 20cm/1cm. This gives us a cube with dimensions 8x15x20.

Now, to find out how many cuboids we can fit inside this cube, we need to calculate the volume. The volume of the cube is calculated by multiplying all three dimensions together: 8 x 15 x 20 = 2400 cubic centimeters.

Therefore, you can fit 2400 cuboids with dimensions 8cm x 15cm x 20cm stacked together to form a cube. That's a whole lot of cuboids! I hope they enjoy their cozy new home.

To determine the number of cuboids with dimensions 8cm x 15cm x 20cm that can be stacked together to form a cube, we need to find the greatest common divisor (GCD) of the three dimensions.

The GCD of 8, 15, and 20 is 1.

To form a cube, the GCD of the three dimensions must be a common factor of each dimension. Since the GCD is 1 in this case, it means that we cannot stack these cuboids together to form a cube.

To find the number of cuboids with dimensions 8cm x 15cm x 20cm that can be stacked together to form a cube, we need to determine the dimensions of the cube that can accommodate these cuboids.

The volume of each cuboid is given by multiplying its three dimensions: 8cm x 15cm x 20cm = 2400cm³.

To determine the dimensions of the cube, we need to find the cube root of the total volume of all the cuboids stacked together. The total volume is given by the number of cuboids multiplied by the volume of each cuboid.

Let's assume the number of cuboids is "n".
The total volume = n * 2400cm³

To find n, we need to calculate the cube root of the total volume. Mathematically, it can be represented as:

n = cube_root(total volume / 2400)

Once we find the value of n, we will have the number of cuboids that can form a cube.

Please note that the cube root operation may result in a non-integer value. In that case, you would need to round up or down to the nearest whole number since you can't have a fraction of a cuboid.

So, to find the number of cuboids with dimensions 8cm x 15cm x 20cm that can be stacked together to form a cube, follow these steps:

1. Calculate the total volume of the cuboids: total volume = 8cm * 15cm * 20cm = 2400cm³.
2. Take the total volume and divide by 2400 to get the number of cuboids: n = cube_root(total volume / 2400).
3. Round up or down to the nearest whole number to get the final number of cuboids that can form a cube.

Hope this helps!

8*15*20 = 2^5 * 3 * 5^2

you want the product to be a perfect cube, so you need
2 * 3^2 * 5 = 90 cuboids
